In this Aug. 3, 2016, photo, Democratic presidential candidate Hillary Clinton arrives at a rally at Adams City High School in Commerce City, Colo. Clinton doesn’t appear all that interested in making any scenic stops on her state-to-state quest to become president. The Democratic nominee is instead programming her GPS to take her on the quickest route to collect the 270 Electoral College votes she needs to win the White House.

Hillary Clinton now holds a 10-point lead over Donald Trump, 51 percent to 41 percent, according to results from the latest NBC News|SurveyMonkey Weekly Election Tracking poll.

Clinton's double-digit lead is up from an 8-point gap last week. The 10-point margin is the biggest spread in the tracking poll since the two-way general election match-up was first compared in early May.

Over the past four weeks, Trump has lost support from core Republican voters. In previous weeks, the Republican nominee dominated Clinton among men. This week, however, Trump's margin over Clinton among men is only 5 points, down from a 16-point margin two weeks ago.
